Abstract (en)

[origin: EP2950054A2] A resolver (100) is disclosed in which the number of turns and the winding direction of a cosine-phase coil (17) wound around an i-th tooth (11) and the number of turns and the winding direction of a sine-phase coil (19) wound around the i-th tooth are set according to T c,i = T Smax cos(m s ¾ i + ¸ 2 ) + T 2c cos(m e ¾ i + ¸ 1 ) and T s,i = T Smax sin(m s ¾ i + ¸ 2 ) + T 2s cos(m e ¾ i + ¸ 1 ), respectively, where T Smax : a first reference number of turns of each of the detecting coils of each phase, T 2c : a second reference number of turns of each of the cosine-phase coils, T 2s : a second reference number of turns of each of the sine-phase coils, m e : a pole pair number in a magnetic flux distribution formed by the exciting coils, m s : a pole pair number in each magnetic flux distribution formed by the detecting coils of each phase, ¸ 1 : the phase of the exciting coils, ¸ 2 : each phase of the cosine-phase coils and the sine-phase coils, and ¾ i : a mechanical angle of the i-th tooth (11).
